I absolutely love this cream. I bought a 110gm tub to try and now I am buying the 400gm tub. I rub the cream on my knees before my Jazzercise classes and I can feel the heat during and after classes which is what I need. Greendragon is the best I have ever tried. I have 3 very sporty boys that use it as well, they also think it is the best they have used. I recommend it to everyone.
